Getting Started

Double-click the Google SketchUp icon

or click:Start →All Programs →Google SketchUp 7 →Google SketchUpStart →All Programs →Google SketchUp 7 →Google SketchUp

The start screen should look something like this:

SketchUp “Inferences”

One of SketchUp’s key strengths is that it doesn’t require you to enter every little piece of information as many 3D computer programs do. Instead, it tries to infer what you really mean by how you do things. Oftentimes it uses colors to tell you what it is inferringOftentimes it uses colors to tell you what it is inferring.

• Green dots = Endpoints• Red dots = On an edge• Cyan dots = Midpoints of edges• Cyan dots = Midpoints of edges• Blue dots = On a surface

• Red line = X axis• Blue line = Y axis• Blue line = Y axis• Green line = Z axis

• Magenta line = something is parallel or perpendicular to an edgeperpendicular to an edge

• Hold SHIFT to capture and lock an inference

Axis Coordinate System

This is called The Origin

Exporting an Image File

Click File→Export →2D Graphic

Your image can be exported inYour image can be exported in one of 4 formats:

1. BMP

2. JPEG

3. TIF

4. PNG4. PNG

You would do this, for example, to email someone an image of your scene to import it someone an image of your scene, to import it into a document, or to put it on your website

You can also export the 3D scene, but in the free version only to Google Earth

the free version, only to Google Earth format. For more 3D formats, you need the Pro version.

Changing the Person’s Clothing

The person in the default scene is a SketchUp“Component”, that is, he is a p , ,group of geometry collected together. To change his clothing, you need to first break, or “Explode”, the , p ,collection apart.

Even easier, right-click on the person and select pExplode from the pop-up menu.

After that, you can click on Window→Materials and re-color or re pattern the clothing

or re-pattern the clothing

Creating Groups

Sometimes you would like to collect several pieces of geometrySometimes you would like to collect several pieces of geometry together and be able to treat them as a single unit. This is called a SketchUp Group.

Create a SketchUp Group by first clicking on the Select iconCreate a SketchUp Group by first clicking on the Select icon.

Then, click on the first object you want in the Group. It will turn blue.

Then, hold down the Shift key and click on all other objects you want in the group. They will also turn blue. If you select the wrong item, just click it again to un-select it.

You can select many things at once by creating a rectangle around all of them with the Select cursor.

When you are done, right-click and select Make Group fromWhen you are done, right click and select Make Group from the pop-up menu.

To ungroup the objects, right click on them and select Explodefrom the pop-up menu.

from the pop up menu.

Hiding Geometry

Sometimes it would be nice to temporarily eliminate some geometry so that you could see inside something This is referredinside something. This is referred to as Hiding.

To hide one or more pieces of geometry select all of them as ifgeometry, select all of them as if you were about to create a group.

Then, right-click and select Hidefrom the pop up menu Thefrom the pop-up menu. The selected objects look like they are gone, but they aren’t. They’re just hidden.

This is useful for putting things into an object (such as furniture) or for editing the object (as is needed here)

Un-Hiding Geometry

There are two ways to bring back hidden geometry.

The first is to select Edit→Unhide→All, like this:

The second is to selectThe second is to select View→Hidden Geometry. This will make hidden geometry show up like this:From there, you can right-click on it and y gselect Unhide from the pop-up menu.

Eliminating GeometryEliminating Geometry

Sometimes extruding geometry results in it existing places it shouldn’t.

To eliminate any geometry, take the Eraser tool and click on the edges of the geometry you want to eliminate.

As soon as an edge of a surface has been eliminated, the surface will disappear too.pp

Move Tricks

You can turn the Move into a Copy by holding down the Control key.

You can force the Move/Copy to move along one of the 3 axes (red, green, or blue) by holding down one of the arrow keys as follows:

Drawing an Arc

1. Click on the Arc Tool

2. Select two points for the chord

Offsetting a Surface

1. Click on the Offset Tool

2. Select the surface to offset on

3 Move the mouse to show how3. Move the mouse to show how much to offset – click when ready

4. This only creates offset edges –you need to use the Push-Pull Toolyou need to use the Push Pull Tool to do something with it.

9. Use the Window → Materials Dialog Box to Add Tile and Water

If you hold down the Control Key when adding the tile y gpattern, it will apply it to all surfaces, not just one. This saves you a lot of time.

Then add the water pattern after that.

Adding Fog

This brings up the Fog dialog boxClick Window→Fog

Click here to turn the fog feature on

This slider adjusts how far in jfront of your eye the fog starts. Items closer to you than this will not be fogged at all.

Adding a Vertical Chimney to a Sloped Roof

1. Draw a line along the roof using the pencil tool. SketchUp’sthe pencil tool. SketchUp sinference engine will try to force it to be parallel to an axis. Let it do that.

2 S l t th li j t d U2. Select the line you just drew. Use the Move/Copy icon with the Control Key held down to lift it up in the air. (The Control key will force it to do a Copy.) Wiggle it a py ) gglittle bit until you get the phrase “On Blue Axis” to appear. This indicates that you are lifting it straight up.


Computer Graphics


3. Draw lines using the pencil tool from the ends of this new line to the face of the roof. SketchUp will t ll h th Btell you when you are there. Be sure the line is a color (red in this case) to indicate that you are parallel to an axis.

4. Using the pencil tool, connect up all the points to form edges. You should have 9 lines in all. (Don’t forget to look at the back of the chimney ) SketchUp will turn thechimney.) SketchUp will turn the edges into faces as you complete them. There should be 4 faces in all.

5. Use the Push/Pull tool to lift the top surface.

6. Use the Offset tool to make an inner surface on that top surface.

7. Use the Push/Pull tool to push that inner surface down.

10. Unhide the end face when you are done
